| Popis: |
In this paper we will describe the most advanced research we have conducted in the amplification of cw and femtosecond lasers using Ti:Al2O3 amplifiers. We have looked at the possibility to obtain very high gain in regenerative and multipass amplifiers. In order to find the limit of this method we have modelized the multipass amplification using a Frantz-Nodvick model [1]. To be reliable, this model needs a precise value of the saturation fluence of Ti:Sapphire. As the plublished values present a great disparity we have first measured this very important parameter. In the following paper we will present the results of this measurement. Then we will analyze the possibility of very high gain amplification in Ti:Sapphire. Experimental results using a regenerative amplifier will be presented and at last the results obtained with multipass amplifiers will be described. |
